Good so far. This Dremel is mental. I've had several of the alternatives, like a Black & Decker Wizard that I got when I was about 10, to a cheap one from Maplin that had all the torque of a pull back toy car, and this is is in a different league. It's got so much torque from even the lowest RPM setting, putting it on the work it maintains it's speed so well.
On full it's 33,000rpm, which is 550 revolutions per second!
It's fast approaching Beer O'Clock
